Can I contribute the replacement property to a partnership right after the exchange?

The words 'to be held' apply to you, and they are tested at the exchange

Section 1031(a)(1) defers gain only if the real property received "is to be held either for productive use in a trade or business or for investment". The person who has to hold it is the taxpayer doing the exchange. If your plan at closing is to hand the property to a partnership, the IRS can argue that you received a partnership interest in substance, and an interest in a partnership is not real property under Reg. section 1.1031(a)-3(a)(5).

The courts frame holding as intent. In Bolker v. Commissioner, the Ninth Circuit held that a taxpayer who owns property he "does not intend to liquidate or to use for personal pursuits" is holding it for investment. That standard looks at whether the investment continues, not at whose name is on the deed six months later.

Magneson allowed a same-day contribution, but in one circuit and on its facts

The Magnesons exchanged an apartment building for a 10 percent undivided interest in a commercial property and, the same day, contributed that interest to a limited partnership for a general partnership interest. The Tax Court allowed deferral and the Ninth Circuit affirmed, reasoning that the contribution under section 721 was "a continuation of the Magnesons' investment unliquidated but in a modified form".

The same opinion describes Rev. Rul. 75-292, in which the IRS ruled that property exchanged and then transferred to a controlled corporation under section 351 was no longer held by the taxpayer, so gain was recognized. The court distinguished the ruling rather than overturning it, and it remains the IRS's published view for corporations.

Outside the Ninth Circuit, there is no appellate decision on point opened for this page. Treat Magneson as an argument you could make in an audit, not as a rule you can plan around.

The contribution is tax-free, but the partnership adds its own seven-year clocks

Section 721(a) says no gain or loss is recognized on a contribution of property to a partnership for an interest in it. That keeps the contribution itself quiet, but it carries your low basis into the partnership.

Two rules then watch that built-in gain. Under section 704(c)(1)(B), if the partnership distributes the property you contributed to another partner within 7 years, you are treated as recognizing the gain. Under section 737, if you receive other property in a distribution within 7 years of contributing, you can recognize gain up to your net precontribution gain.

Worked example: a planned contribution two weeks after closing

Hypothetical, round numbers; run your own numbers with your CPA. You sell a rental for $2,000,000 with a realized gain of $900,000 and buy a $2,000,000 building. Two weeks later, as agreed before closing, you deed it to an LLC with two partners for a one-third interest.

If the IRS argues the building was never held by you and wins, the exchange fails and the $900,000 gain is taxed in the year of your sale, at up to 25% on the depreciation layer and up to 20% on the rest, plus the 3.8% [net investment income tax]({L('niit')}) where it applies. The contribution would have been tax-free under section 721; the problem sits in the exchange, not the contribution.

Contrast taking title from day one as tenants in common with your partners, each partner closing their own share of the purchase. Each of you then holds real estate directly and can form the LLC later, after a period of holding that reflects a real investment.

What to do instead, and where a trust interest fits

If the goal is co-ownership with partners, build it into the purchase rather than after it. If the goal is liability protection, a single-member LLC owned only by you is disregarded and changes nothing for section 1031, as explained in moving a 1031 from your own name into an LLC. Admitting members later is a separate event; gifting or transferring the replacement afterwards covers what the courts have done with later transfers.

There is no published waiting period. How long to hold before a contribution is a judgment about facts, which how long to hold the replacement and drop-and-swap strategies explore.

If what you want is pooled, passive ownership, a beneficial interest in a Delaware Statutory Trust is bought as replacement property in its own right, so there is no later contribution step. The structural differences are in DST versus TIC.
